Score of a life time!
SparWeb:
Those are fascinating pictures XP. Thank you!
There are a lot of spliced wires going in and out of the battery faces. Are those your modifications or did the batteries come like that?

Those are for the cell heaters, they use two 1450watt pad heaters running off the 77v dc rail (So One battery rack has 2, so a total of 6 in the assembly as a whole)
That battery is factory I have done 0 to it at this point other then recovering the cell stacks by a very low constant current charger (24v 4Amp lead acid charger)

Thanks for the confirmation.
That helps me see the picture.
Any company that makes battery stacks like these ones, with extruded-profile cases, 19-inch rack mounting, Aerospace standard power receptacles, day-glow high-voltage power cables, and military circular connectors, has really screwed the pooch when they also have wires slipping in and out of the cooling vents, crimp-spliced to heating pads.
Did somebody say "last minute change in engineering"!?

and uses two small course thread screws into the phenolic resin to retain the DC- cables!
Top shelf components, bottom shelf assembly in a lot of areas, the connectors are bolted! so easy to re task for your own stuff.
12v and 24v DC-DC converters too! 400 dollar contractors! good grab bag of goodies

https://www.ebay.ca/itm/403912335120? < BMS for 25V
I'd recommend getting the touch screen with it, far more useful to get stats with out needing phone
if you get the battery any ways
